Kupros: Copper in the history of Cyprus ...

Copper has been critical in the history of Cyprus - the Greek name for the ore - kupros - comes from the word Cyprus. A Cyprus Museum display (now disappeared) estimates that 200,000 tonnes of copper ingots were extracted by ancient workings from the Troodos ore

Mining history of Cyprus - Copper mines Euromines

The mining industry of Cyprus was active in the production of minerals of copper, iron pyrite, gold, chromites as well as asbestos fibers. Since 1979 the mining industry of Cyprus is in recession because of the exhaustion of the known large and rich copper and iron pyrite ore

Geologically the ore genesis model shows Cyprus’ copper deposits were created by volcanic activity. A better understanding of how the ore was formed has allowed Hellenic Copper Mines Ltd. to utilize extraction methods which result in higher yields. Their copper exports from the Skouriotissa mine were valued at US$13.1 million during 2010. As another example of increasing production based on ...

The Mines Service - Mines - Copper and gold

The mining history of Cyprus has connected the name Cyprus, with the name of copper (Cuprous). The production of copper in Cyprus began 3000 BC on a full scale. The ancient Cypriots were not only experienced miners but also skilful metallurgists. They discovered almost all copper ore bodies which have been exploited in modern years, and they were able to recover the rich part of the ore bodies ...

01/01/2020  Copper mining in Cyprus dates back to the Early Bronze Age and continued in Phoenician and Roman times (Knapp et al., 1998). With the collapse of the Roman empire, mining in Cyprus declined and eventually ceased sometime around the fourth century. Around the beginning of the twentieth century several ore companies explored the area which led to larger-scale mining activities,

Lefke - Cyprus Mining Corporation (CMC)

During his research around Lefke he discovered big amount of copper-ore and sulfides on Foucassa hill. Philip Wiseman and Seeley Wintersmith Mudd, who were the owner of the mining cooperations in US have been informed by Gunther that there could be copper- ore in Cyprus. Afterwords they started operating the copper mine on Foucassa hill. At this stage some drilling machines and experts have ...

Supergene (geology) - Wikipedia

The reaction produces secondary sulfides with metal contents higher than those of the primary ore. This is particularly noted in copper ore deposits where the copper sulfide minerals chalcocite Cu 2 S, covellite CuS, digenite Cu 18 S 10, and djurleite Cu 31 S 16 are deposited by the descending surface waters. All such processes take place at essentially atmospheric conditions, 25 °C and ...

VOLCANIC-ASSOCIATED MASSIVE SULFIDE DEPOSITS (MODELS

Cyprus-type deposits (Model 24a; Singer, 1986a) tend to be small, medium-grade deposits rich in copper and zinc. They are generally lens or mound shaped accumulations of massive pyrite developed in ophiolite-related, extrusive basalt sequences. They are typically underlain by copper-rich "stringer-zones" composed of anastomosing quartz-sulfide mineral veins in extensively chloritized basalt ...

LEAD ISOTOPE CHARACTERISTICS OF THE CYPRUS

Nearly 200 new lead isotope analyses of sulphidic and oxidized ores from 26 copper mines on Cyprus show that the mines from different geological regions group in five distinctive isotopic groups, each with a substructure, related to the geological history of the ore formation. Comparison of lead isotope compositions of Bronze Age artefacts with these data can in many cases reveal the actual ...
